MCP4726A1T-E/CH

Digital To Analog Converters Overview

The MCP4726A1T-E/CH is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring an I²C serial interface and nonvolatile EEPROM memory. It operates on a single supply voltage ranging from 2.7V to 5.5V. The device provides rail-to-rail analog output with a typical settling time of 6 µs. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (3.4 Mbps) I²C modes. Power consumption is typically 210 µA during normal operation and drops to 60 nA in power-down mode. The component is housed in a compact 6-lead SOT-23 package.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM for automatic recall of DAC register settings and device configuration upon power-up.
• Configurable output gain options including unity (1x) and 2x when utilizing the external VREF pin.
• Multiple power-down modes allowing selection of output buffer disconnect or specific pull-down resistor values.
• Supports eight available I²C addresses for flexible multi-device bus configurations.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'E/CH' against the manufacturer's current datasheet to confirm compliance with RoHS directives and material declarations. Ensure the selected package variant matches the required PCB footprint specifications. Confirm that the operating temperature range aligns with the intended environmental conditions before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when a 12-bit resolution is required for precise analog signal generation. Consider the MCP4706 or MCP4716 if lower resolution meets system accuracy requirements while maintaining similar interface characteristics. Evaluate the need for external reference voltage versus internal VDD reference based on desired output stability and gain configuration.

Digital To Analog Converters Part Context

This component belongs to the MCP47X6 family of voltage output DACs manufactured by Microchip Technology. The series includes the MCP4706 (8-bit), MCP4716 (10-bit), and MCP4726 (12-bit). All members share identical pinouts, I²C interfaces, and nonvolatile memory features, differing primarily in resolution and associated accuracy metrics.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include the MCP4706A1T-E/CH and MCP4716A1T-E/CH. These parts maintain identical pinouts and software compatibility but offer reduced resolution. Verify that the lower resolution meets the specific application's accuracy requirements before substitution.
